You should call your doctor immediately if you develop any side effect while taking a drug. If you do develop side effects it is vitally important that you speak to your doctor before you stop taking your pills. Remember that this list of side effects isnít complete - you can develop virtually any side effect with virtually any drug - and remember too that some of these side effects are quite uncommon and many patients can take a drug without getting any side effects. Always follow your doctorís advice about how and when to take a drug - and if you are in any doubt at all then ask for a second opinion. The fact that one drug may be accompanied by a long list of possible side effects does not mean that it is necessarily more or less dangerous or more or less likely to produce problems than a drug which has a shorter list of possible side effects.
